Melt your stick of butter in a bowl, and in another bowl, combine brown sugar and cinnamon. Remove biscuits from the tubes and roll each into a ball. Roll each ball first in the melted butter and then in the brown sugar/cinnamon mixture. Place in a greased pie plate and bake for about 10 minutes (or until the inside of the biscuits are done.) While those are cooking, in a bowl, combine your powdered sugar and a few spoonfuls of the melted butter you have left over. Mix and taste. Too buttery? Add more powdered sugar. Too dry? Ad a bit more butter. Remove biscuits from the oven (Be aware this is going to make your house smell AMAZING!) Pour your icing over the hot biscuits and enjoy!
